If you are not getting any lights when you plug in and turn on power switch. These would be the steps I would follow, make sure on/off switch is functioning, 15 amp fuse is good or any fuse on power supply board, make sure power is coming out of power supply board. Power supply is the board with the power cord coming up to. Hope this helps. Should have a tech familiar with this machine check.

Sharp ar-337 driver windows 7

This machine is to old. Sharp does not support drivers for these anymore. Try using an HP driver and configure the port to the IP address of the Sharp 337. You will not have any finisher functions, but you should be able to print.

I have a sharp AR-337 copier, On the dispaly it reads: CALL FOR SERVICE. CODE:H4-00

H4 00 Heat roller abnormally low temperature

The fusing temperature does not reach 175C degrees within 30 sec of turning on the power, or the fusing temperature keeps at 140C degrees.

C/I/0/I code 14. If it doesn't reset probably a blown thermostat on those piece of **** fusers. Also have seen the lamps some, mostly thermostat. If it has many miles on it I'd just replace the fuser.

If the previous methid wont work..., Clear --> Density select --> Clear --> Density select is for service mode.
Check code 26-30 and set to 0 - CE mark support control OFF
Try surge arrest power source.

Hope helps

Looking for a Feeder unit for a Sharp AR-337 ????

The AR337 comes with a standard document feeder with a model number of AR-RF1. If you're looking to purchase one from a 3rd-party or from Sharp you'll need to reference that model number.

Hello, I have a Sharp AR-337 and I am getting a message: "Call for service. Code: H5-01" is there anything i can do to fix this?

Hello sir; I like you check the exit senser first see does it move freely, if yes, then do a reset procedure; press "program", "interupt", "clear", "interupt" then enter 14 press start, turn power off and back on.
